Retención de sedimentos, nutrientes y glifosato por ecosistemas ribereños en paisajes agrícolas de la Pampa Austral
Giaccio, Gustavo Carlos María (Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2017-05)En este estudio se analizaron algunos aspectos relacionados al efecto de la invasión de Salix fragilis sobre la reducción del flujo de escorrentía y retención de sedimentos, glifosato, nitrógeno y fósforo en ambientes ... -
Sampling scheme optimization to map soil depth to petrocalcic horizon at field scale
Domenech, Marisa Beatriz; Castro Franco, Mauricio; Costa, Jose Luis; Amiotti, Nilda Mabel (2017-03-15)Soil depth has played a key role in the development of soil survey, implementation of soil-specific management and validation of hydrological models. Generally, soil depth at field scale is difficult to map due to complex ... -
Soil physical properties under different cattle stocking rates on Mollisols in the Buenos Aires Province, Argentina
Frolla, Franco Daniel; Aparicio, Virginia Carolina; Costa, Jose Luis; Kruger, Hugo Ricardo (2018-09)This study evaluated the impact of different cattle stocking rates on different soil physical properties in different soils in an integrated livestock no-till agricultural system. We evaluated three stocking rates ... -
Soil properties of sugarcane fields controlling triazine leaching potential.
Portocarrero, Rocio; Aparicio, Virginia Carolina; De Geronimo, Eduardo; Costa, Jose Luis (CSIRO PUBLISHING, 2019-08-21)Atrazine and ametryn are pre- and post-emergence herbicides widely used in sugarcane fields. Both herbicides are characterized by their moderate to high mobility in soil and are regarded as a threat to hydrologic systems. ... -
A spatial dataset of topsoil texture for the southern Argentine Pampas
Castro Franco, Mauricio; Domenech, Marisa Beatriz; Borda, Marta Renée; Costa, Jose Luis (2018-03)We produced a 1-km spatial resolution dataset of soil texture for the southern Argentine Pampas. Variables related to climate have higher prediction performance for soil texture. The soil texture varies gradually becoming ... -
Use of geophysical survey as a predictor of the edaphic properties variability in soils used for livestock production
Peralta, Nahuel Raúl; Cicore, Pablo Leandro; Marino, María A.; Marques da Silva, José Rafael; Costa, Jose Luis (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), España, 2015)The spatial variability in soils used for livestock production (i.e. Natraquoll and Natraqualf) at farm and paddock scale is usually very high. Understanding this spatial variation within a field is the first step for ... -
Variabilidad espacial de suelo a escala de lote y su relación con los rendimientos
Córdoba, Mariano Augusto; Bruno, Cecilia Inés; Costa, José Luis; Balzarini, Mónica Graciela (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-03-23)El manejo sitio-específico dentro de un lote requiere delimitar zonas homogéneas. Múltiples variables, tales como algunas propiedades del suelo, son usadas para la zonificación. El análisis de “cluster fuzzy k-means” (CFK) ...
